Beef Protein Isolate: Beef has proven itself as a favorite anabolic protein source for many champion bodybuilders. MuscleMeds advanced hydrolyzed Beef Protein Isolate is capable of delivering rapid absorption of high concentrations of amino acids. CARNIVOR MASS provides the mass building benefits of beef "at the speed of whey," without the lactose, fat, cholesterol and other problems associated with dairy products. MuscleMeds BPI is 350% more concentrated in amino acids than steak and more concentrated than whey. And it's enhanced with 5 grams of creatine and additional BCAAs for even greater anabolic power!*

iSpike is an exclusive MuscleMeds technology designed to harness the full anabolic impact of insulin. Using fast-acting, reactive-enhanced micronparticulated carbs and the novel insulin potentiators Chromium 454 (Cr454) and D-pinitol (a cyclitol), iSPIKE causes a rapid elevation in insulin while simultaneously amplifying insulin signaling at the muscle receptors to potentiate maximum muscle growth, glycogen replenishment and tissue regeneration. iSPIKE works so fast and is so powerful, don't be surprised if you feel the anabolic impact inside every muscle of your body within 30 minutes of your first delicious serving. This is the desired anabolic effect you want from your mass gainer and it can only be achieved with CARNIVOR MASS...the new breed mass builder from MuscleMeds!*
